having kept and bred rams previosuly(unsuccessfully), i've found thm really finicky creatures that need a specialist, soft water acidic tank, ofen with peat substrate etc, and i've finally given up on them, as, ven afer setting up a special breeding tank for them, i could only raise the fry for a week or so before they all died, and then the female killed the male, happened 3 times before i gave up.
unless you're prepared for this, plus their short lifespans, 2-3years max, then i'd suggest the honey gouramis, they stay small, and are more tolerant of water paremeters, case in point, my LFS keeps them in a slightly brackish system. They're also more active fish generally, rams are often shy, at first at least.
My recommendation would be to go for the honey gouramis
